cloning of container fails (missing root mount point ?)

[GoogleCodeExporter]

Steps to reproduce:
1. select container, (cloning container 100 -> 101)
2. click on tools -> clone
3. enter data (must be reasonable, but the exact values do not matter)
4. -> error message

Actual result: error message: (in web window)

Internal error: Command 'vzctl set 101 --userpasswd root:XXX' execution failed 
with code 6
Output: Starting container...
stat(/vz/root/101): No such file or directory
stat(/vz/root/101): No such file or directory
realpath(/vz/root/101) failed: No such file or directory
Can't umount /vz/root/101: No such file or directory
stat(/vz/root/101): No such file or directory
unable to change dir to /vz/root/101: No such file or directory
Not enough resources to start environment
Container start failed (try to check kernel messages, e.g. "dmesg | tail")
Error: Unable to apply new quota values: quota not running
stat(/vz/root/101): No such file or directory
stat(/vz/root/101): No such file or directory
realpath(/vz/root/101) failed: No such file or directory
Can't umount /vz/root/101: No such file or directory

Expected result: cloned container

Version of the product: 2.1

Server OS: Scientiv Linux 6.3

Browser: FireFox/Safari/Chrome (does not matter)

Additional information:

Debug output of hwdaemon.log:

[...]

The reason for this seems to be that the mountpoint /vz/root/101 is missing.
I checked the hwdaemon.log and there is the command sequence to clone the
container, but no commands for creating the mount point /vz/root/101

adding an experimental 

'hardware_server.rpc_client.exec("mkdir 
/vz/root/#{shellescape(identity.to_s)}")' 

to  ./app/models/virtual_server.rb  solves the problem.
